Specification of Letters Patent.

Patented May a, 1915.

Original application filed June 24, 1913, Serial No. 775,476. Dividedand this application filed January 8, 1914. Serial No. 811,007.

To all whom, it may concern:

Be it known that I, LUTHER T. PAGE, a citizen of the United States, anda resident of l Vareham, in the county of Plymouth and State ofMassachusetts, have invented new and Improved Shaping-Rolls forHorseshoe-Bars, of which the following is a full, clear, and exactdescription.

Among the principal objects which the present invention has in view are:to provide means for mechanically creasing and partially punching thebars from which horseshoes are subsequently made; to prevent thecreeping or misregistering of the rolls with the bars and shoe-formingsections thereof; to-reduce the friction offered by the bars to therolls when passing therethrough; and to provide rolls of the charactermentioned, having a simplified and economical construction.

In the drawings: Figure 1 is a side view, partly in section, of shapingrolls constructed and arranged in accordance with the present invention,the section being taken as one the line 11 in Fig. 2; Fig. 2 is a crosssection taken as on the line 2-2 in Fig. 1; Fig. 3 is a cross sectiontaken as on the line 3-3 in Fig. 1; Fig. l is a detail view showing afragment of the roller bearings employed in conjunction with the rollsat present disclosed; Fig. 5 is a side view of a fragment of a metal barafter being passed through rolls constructed in accordance with thepresent invention.

The herein disclosed construction and claims relating thereto,constitute divisional subject matter disclosed in a co -pendingapplication for Letters Patent, filed by me June 24, 1913, having SerialNo. 77 5,476 for shaping rolls for horseshoe bars, which ap plicationhas ultimated under date of February 10, 1914;, in a Patent No.1,086,933, to which patent cross-reference is here made.

Long bars of metal 15 have imparted thereto elongated depressions orcreases 16, in which, when the horseshoe is secured to the hoof of theanimal, the heads of the securing nails are disposed. The bottoms of thecreases 16 are waved to provide thin sections 17, which are subsequentlypunched through to form holes for the nails by which the said shoes aresecured to the hoofs of the animal. The creases 16 are arranged onthebars by nicks 18. The nickslSare I disposed so that when the bar 15is separated into short segments, the ends having a portion of saidnicks are shaped to form the heels of the completed shoe.

It will be understood that when the straight bar, either in the shape ofshort sections or complete bar lengths, is converted into shoes, theseare shaped about the form by being bent edgewise, the openings of the.

creases 16 being in position to face the ground when the shoe is inservice. What may be termed the final or finishing step in the operationis that where the bars are:

passed between a grooved or female roll and a die or male roll.

To accommodate the different sizes of shoes, the ring 20 is varied,different rings having different diameters, for the reason that it is anessential to the operation of the rings that the punch points 25 shallmark the nicks 13 in the bar 15 at proper intervals to form bars of therequisite length from which to construct horeshoes. The bars 15 are fedat a speed equal to the peripheral travel of a feed roll. As this speedmay vary materially from the speed of the ring 20, it will be seen thata misregister of the punch points 25 may result, and that, further, dueto the variation in the peripheral travel of the ring 20 as compared tothat of the said feed roll, the bars 15 may be curled, necessitating are-handling to straighten them. Further, it will be observed that thevariation in peripheral travel of said ring and roll operates to producefriction.

To overcome the above objection, I form the ring 20 separately. The ring20 is rotatable on the shaft 24:, the end section 27 whereof is providedwith an annular groove to form a bearing for small rollers 28. Therollers 28 likewise extend below the tubular body 29 of'the ring 23. Therings 20 and 23 are spaced apart, as shown best in Fig. 1 of thedrawings, and are held in position by rings or collars 30, formingend-thrust bearings for said rings. Corresponding bearing rings 31 areprovided to receive the thrust of balls 32, which, in conjunctionwithholding rings 33, form a thrust bearing for the rings 20 and 23.

The end section 27 is provided with a shoulder to resist the thrust of aclamp nut 35 when exerted to press upon the ring 31 and intermediatemembers, including the rings 20 and 23. The nut 35 and a follower nut 36are mounted upon a screwoverhanging wall LO is closed, when in service,bya screw 4:1, as seen best in Fig. 4 of the drawings. It willbeobserved that when thus constructed and mounted, the rings 20, and.23, are independently and freely rotatable on the shaft 24:. VVhen, nowthe bar 15 is underthe ring 20, said bar operates to rotate said ring,the periphery whereof travels in unison with, the engaged surface ofsaid bar; or, in other words,'the ring 20 rotates as an idler, at aspeed uniform with the bar 15. By reason of this construction, theopposite surfaces of the bar travel at the same rate of speed, andtheslippage, curling and misregistering of the points 25 above referredto, do notocour. Likewise, the die sections 42 with which the ring 20 isprovided perfectly register with the bars 15. It will also be observedthat the free'running bearing formed by the rollers 28 and balls 32reduces the friction or drag of the ring 20 and the tubular body 29 ofthe ring 23, thus reducing the required amount of manual exertion, andavoiding the consequent curling of the bar 15.
